please help:)

so i recently updated to 1.1.3 and jb'ed it using i brickr.
but then it just froze so i restarted it and when i turned it back on it wouldnt boot, so i restored to 1.1.1 and then i tried to jailbreak using jailbreakme.com but it just crashes internet and does nothing.
i have tried at least 2 other sites that are supposed to jailbreak without computer.
i then jailbroke it using touchfree but my ipod stayed at 300mb.
now i force restored back to 1.1.1 and once agian tried jailbreakme.com but no help
